AMF model transformer to a form view model used in API components.

Package Exports

  • @api-components/api-view-model-transformer
  • @api-components/api-view-model-transformer/api-view-model-transformer.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@api-components/api-view-model-transformer) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

api-view-model-tranformer

An element to transform AMF's ld=json model into a form view model.

Note, this element does not include polyfills for Promise and Array.from.

The model should be used to build a form view for request parameters like header, query parameters, uri parameters or the body.

Data model

  • binding {String} - one of path, query, header
  • name {String} - property (form) name
  • required {Boolean} - is property required
  • value {any} - Value of the property
  • description {String} - The description of the property
  • hasDescription {Boolean} - Flag describing if the property has a description.
  • properties {Array} - If the model is a type of object it is a list of this model objects.
  • schema {Object} - Property schma information
  • schema.type {String} - Data type of the property
  • schema.inputLabel {String} Label for the form control
  • schema.inputType {String} - type attribute of the input element.
  • schema.pattern {String} - Regex pattern of the property
  • schema.minLength {Number} - String property minimum length
  • schema.maxLength {Number} - String property maximum length
  • schema.defaultValue {any} - Default value of the property
  • schema.examples {Array} - List of examples for the form property.
  • schema.multipleOf {Number} - For numeric values, a step attribute of the input element. Each object may contain name (may be undefined) and must contain value property of the example.
  • schema.minimum {Number} - For numeric values, minimum value of the property
  • schema.maximum {Number} - For numeric values, maximum value of the property
  • schema.isEnum {Boolean} - Flag describing enumerable value
  • schema.enum {Array} - Only if schema.isEnum is set. Values for enum input.
  • schema.isArray {Boolean} - Flag describing array value for the property
  • schema.items {Object} - Lsit of items definitions
  • schema.isBool {Boolean} - Flag describing boolean value for the property
  • schema.isFile {Boolean} - Flag describing File value for the property
  • schema.isObject {Boolean} - Flag describing Object value for the property
  • schema.isNillable {Boolean} - True when it is an union and one of union items is nil.
  • schema.inputPlaceholder {?String} - A placeholder value for the input.
  • schema.inputFloatLabel {Boolean} - Only if placeholder is set. Instructs input control to float a label.
  • schema.isUnion {Boolean} - Flag describing union value
  • schema.anyOf {Array} - List of possible types of the union.
  • schema.enabled {Boolean} - Always true
  • schema.fileTypes {Array} List of file types defined for a file type.
  • schema.readOnly {Boolean} - Nil types gets readOnly property

    • The examples on schema object is a result of processing the shape by api-examples-generator element.

    Example

    <api-view-model-transformer></api-view-model-transformer>
<script>
const amfModel = getAmfFromRamlOrOas();
const processor = document.querySelector('api-view-model-transformer');
processor.amf = amfModel;
processor.shape = extractHeadersForMethod(amfModel);
processor.addEventListener('view-model-changed', (e) => {
 console.log(e.detail.value);
});
</script>

    This example uses getAmfFromRamlOrOas() function where you implement the logic of getting AMF json/ld data. It can be stored in file or parsed using AMF parsers. The extractHeadersForMethod() represents a logic to extract properties that you want to transform. It can be headers, query parameters or body type.

    ld+json context

    JSON schema may contain @context property. It can be used to reduce size of the schema by replacing namespace ids with defined in @context keyword. For the component to properly compute AMF values the full AMF model has to be set on amf property.
